ANTI-STATIC POLYESTER FILM AND MANUFACTURING METHOD THEREOF

摘要

PURPOSE: A manufacturing method of an antistatic polyester film is provided to provide an antistatic polyester film which has excellent antistatic performance, minimized deviation of the antistatic performance, transparency, separation from an adhesive tape, anti-staining performance, and coatability. CONSTITUTION: A manufacturing method of an antistatic polyester film comprises an antistatic layer coated on a polymer resin-containing antistatic coating composition by an inline coating method, on one side or both sides of polyester film. The deviation of antistatic performance between an edge part and a center part of the antistatic polyester film is 10% or less. The surface resistance of the edge part and the center part of the antistatic polyester film is 10^7-10^10Ω/sq. The antistatic polyester film satisfies separation force from an acrylate-based tape of 900 g/in or more and separation force from a paper-based tape of 150 g/18mm.
